I think that a good person can sometimes do wrong out of ignorance or weakness or wrong thinking, but when hard times come, the goodness wins out after all. And a bad person can often seem good and trustworthy for a long time, but when hard times come, the evil in him gets revealed.
Someday stars will wind down or blow up. Someday death will cover us all like the water of a lake and perhaps nothing will ever come to the surface to show that we were ever there. But we WERE there, and during the time we lived, we were alive. That's the truth - what is, what was, what will be - not what could be, what should have been, what never can be.
